Brakes bleeding

[geordie john]

Is there anyway round to bleed ABS system without buying expensive diagnostic equipment Thanks. Its on A Renault Master Tag

 

[pappajohn]

Can't see ANS making any difference
I recently bled both rears on my car without problem with ABS.
Doing all four, start at rear N/S...rear O/S....front N/S....front O/S.

thanks watched loads of you tube videos and they were using a computer that operated the ABS pump to bleed the brakes

Bleeding ABS brakes that are already working properly is easy, bleeding ones that may have air in the system is extremely difficult and sometimes impossible without the diagnostic kit as the air can be behind the ABS valves and therefore trapped.
I am not suggesting that you try this on anywhere other than totally private land but if you can drive fast enough to operate the ABS it usually can move any trapped air to the brake lines. This is NOT a suggestion as such a test is to drive a few tonnes at speed with faulty brakes.

all i got here are farmers fields and a 5 ton motorhome i would just sink

Changed my fluid in brake and clutch this year. I had it up on blocks and axle stands and SWMBO pumping for me. The usual analogy is furthest point to closest, but not always the case.

This may well help you and no so expensive.

It’s not a great idea but I know some of the back street garages do it for cheapness. Get a mobile tech out with the right tools otherwise you are wasting your time really.

As Derbyshire wanderer says easy to bleed if ABS working, i use a cheap vacuum tool from ebay useful for vacuum testing lines, sensors as well. I realise OP has a REnault but other readers will have Ducatos, and Multiecuscan is capable of this task but its not suggested unless the ABS has been worked on. I used this on brakes and ducato clutch

not had the abs apart. but changed servo and master cylinder thinking that might be the cause. i have a pressure bleeder the one you hand pump up to 20psi. getting a good stream of fluid out all the nipples but still not working

If you are not getting the air out of the ABS pump it probably needs hooking up to a computer to do it right. The problem you were trying to fix might be related to the pump or controller anyway. Just going through the same with my tow car, chasing a phantom fault that we now believe is the ABS controller reporting a fault that isn't there. Replaced the wheel sensor that reported as ok but the system was sending a fault code. Changed the sensor, which is part of the hub assembly as a unit. Still throwing a fault. Tested all wiring and has good continuity. I hate throwing parts at a fault to guess which is bad, but modern vehicles are too clever for no real reason

What is the problem or what is it you are trying to do?
This may help your responses.

what diagnostic kit would i need to bleed renault brakes

 

[pappajohn]

If you are getting an airless stream of fluid at the cylinder nipples I can't see why you have no brakes.
Im wondering if the ABS pump is at fault

 

[TheBig1]

As I recall the Renault Master brake pedal linkage is adjustable. Are you getting full movement on the push rod to operate the master cylinder?

The usual system is main dealer, but as usual it has been hacked

You can put your bleed pressure system on the master cylinder.

Pressure it up and crack open the unions on the abs one at a time.
You’ll know if there’s air in there.

Make sure if you do this you’ve got plenty of rags or paper around the pump.

HTH

A messy solution, but have had to resort to that before

When needs must and all that.

I’ve got a Snap on Solus but didn’t have the stupid round plug that Merc use to plug in with

So we just cracked open each joint.
Worked a treat if you’ve got one of the pressure bleeders

Not sure what would be cheapest option but this might work. Limited options for any aftermarket ABS diagnosis and manufacturers usually have a monopoly on non emissions related components as there is no legal requirement to allow general scanning.
